GEOLOGICAL-GEOTECHNICAL AERIAL PHOTO INTERPRETATION

GEOLOGISK-GEOTEKNISK FLYGBILDSTOLKNING

This method is used increasingly for outline surveys for planning purposes. The aerial photographs give a rough classification of geotechnical conditions and indicate areas which merit further study. The photographs are interpreted using stereoscopes or a Wild A8 stereoscopic instrument, the soil type boundaries being directly transferred from aerial photograph to ground map. It is possible to distinguish between rock, moraine, coarse sediment, fine sediment and organic soils. Interpretation must always be combined with field surveys and comparisons with previous investigations. A survey of this type was performed on the Brannas Peninsula in order to provide geotechnical data for a proposed industrial development. /TRRL/
